We look at the division of 52782730 by 786 
The aim is to understand the frequency of 786 in 52782730.

On to step 1:
If we divide 5 by 786, we get 0 and a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 786

On to step 2:
When dividing 52 by 786, we get 0 with a remainder of 52.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 52, we get 52.
Take the next digit (7) from the dividend and append it to 52, then repeat: 527 / 786

Moving on to step 3:
786 goes into 527 0 times with a remainder of 527.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 527, we end up with 527.
Grab the next digit (8) from the dividend, add it to 527, then carry on: 5278 / 786

On to step 4:
786 can be fit into 5278 6 times, resulting in a remainder of 562.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Deduct 4716 from 5278 and we're left with 562.
Grab the next digit (2) from the dividend, add it to 562, then carry on: 5622 / 786

Going ahead to step 5:
The number 786 fits into 5622 7 times, leaving a remainder of 120.
The next digit of our result is 7. 
Result so far: 67.0
If we subtract 5502 from 5622, we get 120.
Grab the next digit (7) from the dividend, add it to 120, then carry on: 1207 / 786

Going ahead to step 6:
The number 786 fits into 1207 1 times, leaving a remainder of 421.
The number 1 becomes the next digit in our result. 
Result so far: 671.0
If we take 786 away from 1207, we end up with 421.
Append the next digit (3) from the dividend to 421 and continue with: 4213 / 786

Going ahead to step 7:
If we divide 4213 by 786, we get 5 and a remainder of 283.
Put 5 as the next digit of the answer. 
Result so far: 6715.0
If we take 3930 away from 4213, we end up with 283.
Bring next digit (0) of the dividend behind the 283 and repeat the process: 2830 / 786

Going ahead to step 8:
The number 786 fits into 2830 3 times, leaving a remainder of 472.
The next digit of our result is 3. 
Result so far: 67153.0
If we take 2358 away from 2830, we end up with 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

Let's proceed to step 9:
786 goes into 4720 6 times with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 67153.6
Deduct 4716 from 4720 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 10:
40 divided by 786 is 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 67153.6
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 11:
When dividing 400 by 786, we get 0 with a remainder of 400.
Put 0 as the next digit of the answer. 
Result so far: 67153.6
Deduct 0 from 400 and we're left with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

After the division, we end up with 67153.6 and a remainder of 0.04.
